4.0L Mustang- Track Times Anyone?

Make sure you look into your fuel system before you spray on that ****er...I used to have a 99 GT and was all set to buy a regular EFI Ford when I found out that the 99+ Ford motors use returnless fuel systems, and dry kits don't work with them. I'm not a fan of wet kits on modern EFI cars, as fuel is not meant to travel through modern intake manifolds.

My only plans for sure are tune, intake, exhaust and possibley gears. If i get the need for speed ill add some headers and maybe like a 50-75 shot.

I am getting mixed signals on the different gears, I have heard some say it has hindered their times with the 4.10s and others have not said, I am pondering new gears but I have an automatic, so I do not know if they will do anything for me.
I sure wish I had the extra cash for new headers thats for sure.

They will lower the gear ratio, enabling you to get to higher rpm's quicker, as well as more umph overall. Take for instance a 2 speed drill, in first, its slow, but can tear your arm off, though the motor is running say 10000 rpm's. in second, same 10000 rpm's, but different ratio to make bit faster, thus not as much torque, and wont be able to rip your arm off. (my weird analogy)

1st hits around 40, not sure exactly.
2nd gear hits about 70mph (i push my gears by the way)
3rd hits between 102 and 103
and 4th, who knows, and 5th ill never know.

I think the rear end is diff from the autos to manual (3.31 to 3.55?) but im not sure about the actual gearing in the trans. I do know that the automatics cut you short on redline by 150-200rpm in higher gears, its the computer at work.
